WATER-HEATER.-

Application filed December 27, 1911. Serial .d'o. 66%,043.

To all whom it may concern:

Be it known that 1, PETER A. DnAsr, a citizen of the United States, residing at Oakland, in the county of Alameda. and State of (.alifornia' have invented certain new and 'iseful Improvements in 'Water- Heaters, oi which the following is a specification.

This inveition relates to Water heaters and has special reference to a type of water heater having acentral heating flue, and the principal ol ject of the invention is to im: prove the general construction of heaters of this character so that dilterences in expansions of the parts may be accommodated.

A secondobjecl of the invention is to provide a device of this character wherein the means used to accommodate the differences in expansion will also afi'ord increased heating surface.

A third object of the invention is to provide means for eliminating the condensation caused by the burning of gas.

With the above and other objects in view, the invention consists in general of cer-,

tain novel constructions, arrangements and combinations of parts as will be hereinafter fully described, illustrated in the accompanying drawings, and specifically claimed.-

In the accompanying drawings, like charactors of reference indicate like parts in the several views, and Figure 1 is a vertical median section through aheater constructed in accordance with this invention. Fig, 2 is a side elevation of a heating element used herewith the same being partly in section. Fig. 3 is an enlarged detail view of a certain expansion member used in connection herewith. Fig. 4 is a section on the line 4-4, Fig. 1.

In the present embodiment of the inven tion there is rovided a cylindrical shell on its upper end a head 11 and rests on a suitable support 12. At the lower end of the shell there is provided a frusto-conical bottom 13 corrugated in horizontal rings as can be seen by reference to Fig. 1. This bottom is securely riveted to the shell as at 14 and its upper end forms means 15 threaded interiorlyhtor the attachment of a central flue which con-- sists of a lower section 16, the lower end of which is screwed into the means 15,41 central portion 17 which is provided with horizontally arranged corrugations as best thereof. This casting is hollow and is seen in Fig. 8, and the upper sectidn which passes through the head 11 and has fitted thereon a time the corrugations at the bottom and sec $10115 17 permit the uneven expansion oi the shell 10 and the central fine without bring ing undue strain upon the part. The central portion 17 may, if desired, be made lighter than the end sections 16 and 18 so as to more Patented June23,

pipe 19. By means ofthis arrangement an increased heatingsurface is provided at the bottom while at the seine in a tubular screen 21 which passes up the central flue as can be seen by reference to the drawing.

The heater element consists of a substantially conoidal casting provided with annularly disposed shoulders 22 arranged to form a series of steps on the outside and corrugated interiorly as indicated at 23, the casing being also provided with passages 24 leading from the interior to the exterior vided with a threaded portion 25 for thsattachmcnt of an inlet pipe 26 while from the upper end of the casting extends a pipe 27 which passes up the flue and transversely to the top thereof terminates in a downwardly extended end 28 which passes through the head 11. The pipe'QG forms a branch from a water pipe 29 which leads in through the side of the shell 10. At 30 is a third pipe by means of which the water mav be drawn off as desired. Beneath the heater clement there is provided a as burner 31 of any preferred form which is supplied by gas through a pipe 32 controlled with a valve 33.

It is to be observed that when the device is started in operation a certain amount of moisture will be con'dcnscd on the heater element and will fall down into the grooved shoulders 22 where it will remain until the element has been heated sulliciontly to cause rctivaporation whereupon the ll'lUlSl'lll'i will pass off through the line. t will also be noted that any condensation on the bottom of the line will m-cumulalo. on the son-on 20 so that a large surface will be exposed and it will readily reevaporatc without dripping down from the screen. This screen furtherheating surface so that the heated air pass ing up the flue is in intimate contact with the screen which thus absorbs a greater proportion of the heat and radiates the same to the surrounding flue walls. There has,

thus been provided a simple and eflicient de vice of the kind described and for the purpose specified.

Having thus described the invention What is claimed as new, is: p

A water heater comprising a shell, a bot tom for said shell, a flue leading from said bottom vertically through said shell, a heating drum mounted in said shell beneath said bottom, a pipe leading from said drum through said flue, and a wire fabric mounted in said shell between said drum, and the bottom of said shell and terminating in a fabric sleeve extending'through said flue a said wire fabric at a spaced distance fromsaid bottom, said sleeve positioned at a spaced distance from said flue whereby moisture is spread over the heatinv surface and then caught by said wire f brio for vibration. In testimon whereof I afiix my signature in presence 0 two witnesses I PETERA. DEASY.
